Referring to fig. 2, the utility model provides a magnetic tension paying-off device for producing a steel cord, which comprises a paying-off shaft 10, a spool 20 and a paying-off frame, wherein the paying-off shaft 10 comprises a wire inlet end and a wire outlet end, the paying-off shaft 10 is of a hollow structure, the steel cord enters from the wire inlet end of the paying-off shaft 10 and is discharged from the wire outlet end of the paying-off shaft 10, and a circle of steel wire needs to be wound on the outer surface of the steel cord as an outer winding wire in the process of winding.
The spool 20 is fixed to the pay-off shaft 10, and the spool 20 comprises a first limiting plate and a second limiting plate along the axial direction of the pay-off shaft 10, and a steel wire is wound between the first limiting plate and the second limiting plate; it can be seen that, when the length of the steel wire on the spool 20 is smaller, the angle between the steel wire and the pay-off rack is larger, so that the pay-off rack of the utility model is arranged at one side of the spool 20 close to the wire outlet end of the pay-off spool 10; the pay-off rack comprises a bearing part 31 and a wire passing bracket 32, a wire passing hole 33 is formed in the wire passing bracket 32, and steel wires on the spool 20 pass through the wire passing hole 33 and are wound on the surface of a steel cord discharged from the wire outlet end of the pay-off shaft 10.
Wherein, the wire passing bracket 32 is connected to the bearing part 31 and can rotate relative to the pay-off shaft 10, the wire passing bracket 32 is configured to extend from the bearing part 31 toward the spool 20, and the wire passing hole 33 is located between the first limiting plate and the second limiting plate.
Thus, when the steel wire bypasses the wire passing hole 33, as can be seen by combining with fig. 2, the height of the highest point of the steel wire is obviously reduced, and the angle between the steel wire and the wire passing hole 33 is obviously reduced when the steel wire is paid out between the first limiting plate and the second limiting plate, so that the contact pressure can be reduced, the abrasion of the steel wire is reduced, the wire passing bracket 32 can smoothly rotate, the steel wire can also smoothly slide out of the wire passing hole 33, and the distance between the outer wire wrapping wires is ensured to reach the target range.
Optionally, porcelain tubes are provided in the wire vias 33 of the wire support 32 to improve wear resistance.
Optionally, the wire passing bracket 32 is provided in a bent shape or an arc shape, so that the highest wire passing height is reduced while ensuring close proximity to the spool 20.
In a specific embodiment, as shown in fig. 2-4, the wire passing bracket 32 includes a first bracket 322 and a second bracket 323, a first end of the first bracket 322 is connected to the bearing component 31, a first end of the second bracket 323 is connected to a second end of the first bracket 322, a wire passing hole 33 is disposed at a second end of the second bracket 323, an included angle a between the first bracket 322 and the pay-off shaft 10 is a, an included angle B between the second bracket 323 and the pay-off shaft 10 is a larger included angle a than the included angle B.
Optionally, the angle of the included angle A is 70-80 degrees, and the angle of the included angle B is 40-50 degrees.
Further, the first bracket 322 extends from the bearing member 31 to the height of the first limiting plate, and the second bracket 323 extends to the outer periphery of the first limiting plate.
Therefore, the first bracket 322 can extend to the periphery of the first limiting plate, and the second bracket 323 extends to the periphery of the spool 20 shaft, so that smooth rotation of the first bracket 322 can be ensured, meanwhile, the first bracket is also close to the spool 20, the structure is compact, and the wire routing angle of the steel wire is small.
In an alternative embodiment, the bearing member 31 includes a bearing housing 311 and a bearing ring 312, the bearing ring 312 being rotatably coupled to the bearing housing 311, the wire support 32 further including a fixing ring 312b, the bearing ring 312 being fixed to the fixing ring 312b.
The bearing ring 312 is provided with a first magnetic component, and the bearing seat 311 is provided with a second magnetic component 311a.
Thus, by the interaction of the first magnetic member and the second magnetic member 311a, the tension of the winding wire can be controlled, and by controlling the tension of the winding wire, the pitch of the outer winding wire can be controlled.
Referring to fig. 5-6, the first magnetic member includes a fixed ring 312b and first magnets 312a, the first magnets 312a are distributed in a circumferential array around the axis of the fixed ring 312b, and the second magnetic member 311a includes second magnets. As described above, when the first magnets 312a and the second magnets are brought close to each other, attractive force is formed, and when the number of the first magnets 312a is larger or the magnetism is larger, the interaction force between the first magnetic member and the second magnetic member 311a is larger, and the tension when the wire is wound is larger, it can be understood that the tension of the wire is controlled stably by such magnetic interaction force, and the wire is released more stably.
In combination with the embodiment, the pay-off rack is arranged to extend towards the spool, particularly the wire passing nozzle is close to the axle of the spool, when the steel wire passes through the wire passing nozzle and winds the steel cord outwards, the height of the steel wire is lower, the angle between the steel wire and the wire passing nozzle is smaller, friction between the steel wire and the wire passing nozzle can be effectively reduced, smooth paying-off is kept, paying-off tension is controlled, and the pitch of the outer winding wire is kept.
